Abstract

The invention provides a preparation method of semen pharbitidis extracts. The preparation method comprises the following steps of: S1: smashing semen pharbitidis traditional Chinese medicine materials, and carrying out sieving; S2: dipping the smashed semen pharbitidis in a sodium bicarbonate solution, and then, carrying out concentration to obtain semen pharbitidis powder; S3: dipping the semen pharbitidis powder obtained in S2 in an ethyl alcohol solution; S4: carrying out reduced pressure concentration on dipping liquid to obtain dipped semen pharbitidis powder; S5: adding the dipped semen pharbitidis powder into ethyl acetate to carry out microwave extraction to obtain first extraction liquid and first liquid slags; S6: adding the first liquid slags into the ethyl acetate to carry out microwave extraction to obtain second extraction liquid and second liquid slags; S7: after the first extraction liquid and the second extraction liquid are mixed, carrying out filtering, carrying out the reduced pressure concentration on a filtrate, and carrying out extraction liquid recovery until a solvent is of a paste form; and S8: adding deionized water to carry out dissolving, slowly adding the obtained solution into macroporous resin to carry out purification, standing for 1h, carrying out gradient elution by ethyl alcohol, and then, carrying out the reduced pressure concentration and vacuum drying to obtain the semen pharbitidis extracts.

Description

technical field [0001] The invention relates to the field of extracting active ingredients from the seeds of the petunias, in particular to a preparation method of the extract of the seeds of the petunias. Background technique [0002] Morning glory belongs to the genus Petunias of the family Convolvulaceae, and is also known as Hei Chou, Bai Chou, Er Chou, Morning Glory, and Morning Glory. The colors of morning glory flowers are blue, crimson, peach red, purple, etc. There are also mixed colors, and the edges of petals change more. It is a common ornamental plant. The fruit is ovoid and can be used as medicine. The leaves of morning glory are three-lobed, heart-shaped at the base, and the flowers are white, purple-red or purple-blue, funnel-shaped, and the whole plant has coarse hairs. Split-leaf morning glory is an annual winding herbaceous vine, the whole plant is densely covered with coarse hairs. The top 5 shallow-lobed capsules are spherical, and the seeds are ovate ...
